 The current problem with solar energy is balancing the supply & demand known as the duck curve. The surplus of solar during the day risks over generation and the shortage at night requires more expensive power plants to meet the peak consumption. This caused fluctuations in 2020 daily pricing from $15 to $1500 dollars per MWh. This duck shaped graph shows California's utilities net load in terms of power demand for non-renewable energy for March 31, from 2012 to 2020. Source: California ISO.

Battery storage could offset the challenging supply dynamics of solar power. Over generation can be prevented by storing surplus solar during the day. Then that power can discharge back onto the grid later in the evening when needed during a shortage acting as a Virtual Power Plant (VPP).  This battery to grid Transactive Distributed Energy Resource Management System (TDERMS) reduces the need for curtailment and expensive capital outlays with scalable non-wires alternative solutions.
